Figure 2. Identification of differentially expressed genes (DEGs) in sorafenib resistance. (F) Genes up-regulated in association with sorafenib resistance in HepG2 and Huh7 cells. (G) Genes down-regulated in association with sorafenib resistance in HepG2 and Huh7 cells. (H) Gene set enrichment analysis of genes up- or down-regulated in association with sorafenib resistance in both HCC cell lines.
